Abstract(in English) To clarify whether Irlen syndrome with photophobia had problems in pupillary control, we recorded pupillary light reflex and compared it to a healthy group (n=28). Seasonal decomposition of Time series by LOESS (STL) was used to extract the components synchronized with dark and light stimuli. The results for three experimental tasks with different stimulus duration showed that the patient's pupillary response changed excessively just after stimulation compared with the healthy group. This phenomenon was remarkable with the dark stimulation (mydriasis). These results suggest hyperexcitability of the sympathetic nerve in Irlen syndrome.
